C. resign D. exchangepractice Choose the best answer. This was the call that announced there
was about to be a whale hunt.
这是宣告猎鲸行动马上就要开始的声音。
“that announced there was about to be a
whale hunt”为关系代词that引导的定语从
句，修饰先行词the call。从句中用到“be
about to do sth.”结构，表示将来，意为
“即将，将要”。课文难句精析【拓展】
英语中有很多表示将来时的方法，在具体
运用中表达的内容又不尽相同，现将各种
表达法归纳如下：
①“be going to + 动词原形”，be going to
相当于一个助动词(其中be有人称和数的变
化)，与它后面的动词原形一起构成谓语。
用来表示打算、计划或安排要做的事情，
或在说话时已有迹象预示会在将来发生的
事情。例如：
Look! It’s going to rain.
There is going to be a parents’ meeting
tomorrow.
②“will / shall + 动词原形”，用来表示说话
时认为或预测会在将来发生的动作或存在
的状态。will用于各种人称；shall只用于第
一人称。例如：
What time shall we go there tomorrow?
I will / shall go to visit her next week.③按计划或安排即将发生的动作可以用“现
在进行时”来表示。这些动作往往都与移
动、方向、启动等有关。如：come, go,
arrive, leave, move, fly等。
例如：Mr. Brown is leaving for Beijing
tomorrow.
④在时间或条件状语从句中，表示将来的
动作常用“一般现在时”。例如：
I won’t leave here until you come back.⑤“be about to + 动词原形”意为“正要做某
事、正准备做某事”，通常不接时间状语。
“be to + 动词原形”表示按计划或安排即将
发生的动作，或可能、一定会发生某种情
况。例如：
They are to come to Guangzhou in
November.
⑥用系动词be的一般现在时表示将来。
例如：Are you free tomorrow? I refuse to accept the blame for
something ______ was someone else’s
fault. (2010全国II)
A. who B. that C. as D. what
2. By the time you have finished this book,
your meal ______ cold. (2012北京)
A. gets B. has got
C. will get D. is getting practice Choose the best answer.2. I had already heard that George didn’t
like being kept waiting, so even though I
didn’t have the right clothes on, I raced
after him. 我以前就听说过，乔治不喜欢
等人，所以尽管我还没有穿上合适的衣
服，就跟在他后面跑起来。此句中的so连接的是两个并列句。第一个分句中的从句that George didn’t like being kept waiting作heard的宾语。后一个分句中存在一个由even though引
导的让步状语从句，even though意为“即
使，纵然，虽然，尽管”，其引导的让步
状语从句既可置于主句之前，也可置于主
句之后。例如：本句中出现了keep sb. doing sth.的结构，动名词短语being kept waiting作like的宾语。如：
Don’t keep the girl waiting outside in the
rain.a. Even though I have to walk all the way,
I will get there.
b. I can still remember, even though it
was so long ago.【拓展】
和even though具有同样意思和用法的是
“even if”。 连词as though = as if意为“好
像，似乎，仿佛”，引导方式状语从句。
例如：He behaved as though / as if
nothing had happened. 我一直在想我以前在某个地方见
过她。
(2) 你为什么一直让这个男孩哭?I keep on thinking I’ve seen her before somewhere.
Why do you keep the boy crying all the time?practice Translation.Tim is in good shape physically
_________ he doesn’t get much
exercise. (2010湖南)
if B. even though
C. unless D. as long as practice Choose the best answer.3. It took over half an hour to get the boat
back to James, and when we approached him, I saw James being firmly held up in the water by Old Tom.
我们花了半个小时才把船调转过来，回到詹姆斯落水的地方。当我们靠近他的时候，我看到老汤姆正在水中稳稳地托着詹
姆斯。此句中的and连接的是两个并列分句。
第一个分句中用到了it takes time to do sth.的结构。take在此是“花费”的意思，常用于it takes
sb. time / money to do sth. 意思是“做某事花费某人多少时间/钱”。如：
It took these boys over two hours to finish
this tough task.
第二个分句中存在一个由when引导的时间状语从句，主句中用到了see sb. doing的结构。如：
I saw some children playing on the
playground. 画这幅画花了我两小时的时间。
(2) 买一套房子要花一大笔钱。
(3) 修这条路花了他们三年时间。It took me two hours to draw the picture.
It takes a lot of money to buy a house.
It took them three years to build this road.practice Translation.Tips for teacherLet the word fly 板块是帮助学生学习一些一词多义、熟词生义的词汇。通过此环节，学生可以对一些常见词的用法、意思有一个全面的了解。在翻译过程中体会词汇使用的丰富多彩。backNo?one?can?call?back?yesterday.Choose your goal and never turn back.
